At the bowling alley where Olivia met Sam Weiss last week, she's attempting to tie the laces on her bowling shoes, but her shaky hands aren't cooperating. From behind her, Weiss gives her a tip, which she isn't so patient with, saying she knows how to do it. "Knowing how isn't the issue," Weiss says. "You suffered some wicked head trauma. Don't think about your hands, don't think about the laces. Your shoes will get tied just fine." As he sits down across from her to help her out (so that's how they'll get tied), she asks what he did for Nina. He says he taught her to eat French fries. "Simple enough, unless you've got a cybernetic, prosthetic arm. Nina was a mess." Nice guru-padawan confidentiality there, Weiss. He changes the subject back to shoe-tying. She's about to say she doesn't have time for this when he changes the subject to her sleeping. He claims to be able to tell by looking at her pale skin that she's not getting more than two or three hours. As if it's a shock that an actress with a last name like an IKEA bed sheet would have a face to match. She also admits that she has some lingering pain in her leg and shoulder. He seems surprised that the headaches still haven't started, but says to let him know when they do. And with that, they're done for the night. She looks pretty annoyed, but he's off to mop the men's room. "Come back tomorrow, Agent Dunham. We got work to do." Like she's the one blowing him off. In unrelated news, I didn't realize until this week that Weiss is played by Kevin Corrigan, or as I've always thought of him, "Other Guy From Grounded for Life." Another Fox show I never watched.

At the Fringe lab, Peter is trying to go through apartment listings in the newspaper with Walter. Despite the fact that Peter's clearly meeting him halfway by using a method of apartment searching that went out of wide usage while Walter was in the bin, he's more interested in heating his espresso in a test tube over a Bunsen burner than seriously discussing a new place to live. "I'm perfectly happy with our present accommodations," he declares. Peter impatiently says he isn't, and appeals to Astrid: "I woke up this morning to him singing an aria from Pagliacci." Yes, Peter, you're very cultured. I can't even believe how cultured you are. Astrid compliments Walter's voice, but Peter forgot to add that he was doing jumping jacks naked at the time. So maybe he should have sung something with a little more percussion, then. Astrid puts an end to their bickering by calling them over to her computer (you know, the thing that most normal people use to find apartments these days) to tell them about the train station bombing from the teaser. Except the weird thing is that she's looking at it like some scientific curiosity related to their mission rather than "Oh, my God, someone just blew up a train station in Philadelphia!" She's been spending too much time with Walter. What got her attention is that after an explosion that killed 11 and wounded 28, there were no traces of explosives found. Walter's all excited, and seeing him this way causes Peter to forget his frustration and say, "I'll call Dunham." Walter asks Astrid for his portable chemistry set. "This means bodies!" he says with completely inappropriate enthusiasm. Nothing brightens up the day like a terrorist attack.
